  • Container Isolation Gone Wrong

    One of the main advantages of embracing containers is "lightweight virtualization." Since each container is just a thin layer around the containerized processes, the user gains enormous efficiencies, for example by increasing the container density per host, or by spinning containers up and down at a very fast pace.

    However, as the troubleshooting story in the article will show, this lightweight virtualization comes at the cost of sharing the underlying kernel among all containers, and in some circumstances, this can lead to surprising and undesirable effects that container users typically don't think about.

    This troubleshooting tale is rather involved. I've started from the basics and worked up to the more complex material in the hope that readers at all levels can get value out of it.

  • Introducing Agones: Open-source, multiplayer, dedicated game-server hosting built on Kubernetes

    In the world of distributed systems, hosting and scaling dedicated game servers for online, multiplayer games presents some unique challenges. And while the game development industry has created a myriad of proprietary solutions, Kubernetes has emerged as the de facto open-source, common standard for building complex workloads and distributed systems across multiple clouds and bare metal servers. So today, we’re excited to announce Agones (Greek for "contest" or "gathering"), a new open-source project that uses Kubernetes to host and scale dedicated game servers.

  • Varnish 6.0 Released

    It's that time of March again, and Varnish 6.0.0 is here.

  • HHVM 3.25.0, 3.24.4, and 3.21.8

    HHVM 3.25 is released! This release contains new features, bug fixes, performance improvements, and supporting work for future improvements. Packages have been published in the usual places.

  • HHVM 3.25 Released, Now Defaults To PHP7 Mode

    Facebook developers working on the HHVM Hack/PHP language stack have released version 3.25 of the HipHop Virtual Machine.

    HHVM 3.25's PHP support now defaults to PHP7 rather than the PHP5 mode, which is now in an unsupported state. As expressed previously, Facebook will be focusing more on their Hack language support than PHP7 thanks to all the upstream improvements with PHP 7 especially on the performance front. But the large compatibility with PHP7 will happen to continue at least for the time being. With HHVM 3.25 includes support for PHP7 Throwable/Error/Exception hierarchy, changes to visibility modifiers, and other compatibility work.

  • The P4 Language Grows Up, Joins the ONF and Linux Foundation

    The P4 Language Consortium is becoming a project of the Open Networking Foundation (ONF) and, by extension, a project of the Linux Foundation to which the ONF belongs. The P4 Consortium has been a non-profit organization dedicated to writing the P4 programming language since 2013.

    P4 describe how packets are forwarded by networking devices such as switches, routers, and network interface cards (NICs). P4 takes software-defined networking (SDN) to the next level by bringing programmability to the forwarding plane.

  • P4 Joins ONF & Linux Foundation

    "Linux Foundation is thrilled to welcome the P4 community," said Jim Zemlin, Executive Director at Linux Foundation. "Networking is a major focus at the foundation and the addition of the thriving P4 community combined with Linux Foundation Networking Projects in similar domains will drive innovation in networking to the next level."

  • Mir 0.31 Is On The Way With MirAL 2.0, Wayland XDG-Shell Support

    Ahead of Ubuntu 18.04 LTS next month the Mir developers are working to release Mir version 0.31.

    The focus of the upcoming Mir 0.31 release is on MirAL version 2.0 and Wayland XDG-Shell support. MirAL 2.0 takes a ABI/API cleansing for this Mir abstraction layer to assist in writing code for Mir. This does result in some simplification for users of MirAL.

  • Your first robot: Sharing with others [5/5]

    This is the fifth (and final) blog post in this series about creating your first robot with ROS and Ubuntu Core. In the previous post we discussed methods of control, did a little math, and wrote the ROS driver for our robot. But it still required several nodes to be running at once, and sharing it with the world involved uploading your source code somewhere and convincing people to install ROS, build your package, and use it. Today we’re going to simplify both of those issues by discussing ROS launch files, and packaging everything we’ve written as a snap that can be installed by your friends with a few keystrokes, even without knowing anything about ROS.

  • Ubuntu Desktop weekly update – 16th March 2018

    We’ve had a busy few weeks, and so this email is a roll up of what’s been going on in Desktopland. Last week we had a team sprint in Budapest where we got to work side by side with our teammates and colleagues across Canonical. Feature Freeze has now passed and we’re working on fixing as many bugs as we can. We still have some additional features to land, and so we will be requesting Feature Freeze Exceptions for those. Meanwhile, here’s a recap of what’s been going on:

  • Winning with OpenStack Upgrades?

    On the Monday of the project teams gathering in Dublin a now somewhat familiar gathering of developers and operators got together to discuss upgrades – specifically fast forward upgrades but discussion over the day drifted into rolling upgrades and how to minimize downtime in supporting components as well. This discussion has been a regular feature over the last 18 months at PTG’s, Forums and Ops Meetups.

Government of Jamaica to Actively Pursue Greater Use of Open Source Software – Wheatley

Filed under

Minister of Science, Energy and Technology, Dr. Andrew Wheatley today outlined the Government of Jamaica’s intention to pursue greater use of Open Source Software as part of its thrust to transform ICT within government while at the same time reducing the attendant costs associated with the use of proprietary software.

Guided by recommendations outlined in an Open Source Policy Framework report which was completed in late 2016, Minister Wheatley stated that “It is clear that there are huge benefits to be gained from greater use of open source software by developing countries like Jamaica and we intend to take a more active approach to incorporation of these types of software across government.”

Minister Wheatley in speaking about recurrent enterprise agreements with Microsoft, IBM and other proprietary software vendors said “ for a very long time we have been confined by the strictures and high costs of the license regimes of proprietary software offerings and we will now, in keeping with goals of our Vision 2030 plan, make the move to unleash the innovative capacity of our country by leading the way in the adoption of open source platforms”

  • 3D Printed, Open Source Glia Stethoscope Receives Clinical Validation

    Dr. Tarek Loubani spent some time working in hospitals in the Gaza Strip during the worst of the chaos and violence that is unfortunately still going on there. Due to a long-standing blockade, medical supplies were scarce in the region – so scarce that doctors could often not find a stethoscope when they needed one. So Dr. Loubani came up with his own solution – he 3D printed a stethoscope, for about 30 cents.

What I'm asked for the most though isn't any of those things; it's the everyday stuff that even non-technical people can do to protect themselves from the looming but nebulous threat of an information security accident.

Running a small business is no easy task. The last thing you need is extra complexity in your IT infrastructure – so why turn to Linux?

Well, it could (if you're lucky) actually turn out to be a less complex choice for many tasks, depending on the distribution you select. And, critically, Linux is free; at least if you don't figure in support costs. That's an overhead ticked off the list.

  • Canonical Releases Spectre/Meltdown Patches for Ubuntu 17.10 for Raspberry Pi 2

    Canonical published two security advisories on Thursday to announce the availability of Spectre mitigations for the ARM64 (AArch64) hardware architecture on its Ubuntu 17.10 and Ubuntu 16.04.4 LTS systems.

    In January, Canonical released several kernel updates for Ubuntu 17.10 (Artful Aardvark) and other supported Ubuntu releases with software mitigations against the Spectre and Meltdown security vulnerabilities. These patches were first released for 64-bit (amd64) architectures, and then for 32-bit (i386), PPC64el, and s390x systems.

    Today, the company announced the availability of new kernel updates that address both the Meltdown and Spectre security vulnerabilities for the ARM64 (AArch64) hardware architecture, patching the Raspberry Pi 2 kernel for Ubuntu 17.10, as well as its derivatives.

  • Oracle Patches Spectre for Red Hat

    The Red Hat community has patiently awaited a retpoline kernel implementation that remediates CVE-2017-5715 (Spectre v2) and closes all Meltdown and Spectre vulnerabilities that have captured headlines this year.

    Red Hat's initial fixes rely upon microcode updates for v2 remediation, a decision that leaves the vast majority of AMD64-capable processors in an exploitable state. Intel's new microcode has proven especially problematic; it performs badly and the January 2018 versions were plagued with stability issues that crashed many systems. It is a poor solution to a pressing problem.

  • ​Meet the Scarlett Johansson PostgreSQL malware attack

    t's not the first time an image has been used to give a victim malware, but it may be the first time it's been used so narrowly. According to the security firm Imperva, their StickyDB database management system (DBMS) honeypot has uncovered an attack that places malware, which cryptomines Monero, on PostgreSQL DBMS servers. Its attack vector? An image of Hollywood star Scarlett Johansson.

    Now, you might ask, "How many PostgreSQL DBMS servers are out there on the internet to be attacked?" The answer: "More than you'd expect." A Shodan search revealed almost 710,000 PostgreSQL servers ready to be hacked. It appears there are so many of them because it's way too easy, especially on Amazon Web Services (AWS), to set up PostgreSQL servers without security.

lkml: remove eight obsolete architectures

In the end, it seems that while the eight architectures are extremely different, they all suffered the same fate: There was one company in charge of an SoC line, a CPU microarchitecture and a software ecosystem, which was more costly than licensing newer off-the-shelf CPU cores from a third party (typically ARM, MIPS, or RISC-V). It seems that all the SoC product lines are still around, but have not used the custom CPU architectures for several years at this point. Read more

If you hitch a ride with a scorpion… (Coverity)

I haven’t seen a blog post or notice about this, but according to the Twitters, Coverity has stopped supporting online scanning for open source projects. Is anybody shocked by this? Anybody? [...] Not sure what the story is with Coverity, but it probably has something to do with 1) they haven’t been able to monetize the service the way they hoped, or 2) they’ve been able to monetize the service and don’t fancy spending the money anymore or 3) they’ve pivoted entirely and just aren’t doing the scanning thing. Not sure which, don’t really care — the end result is the same. Open source projects that have come to depend on this now have to scramble to replace the service. [...] I’m not going to go all RMS, but the only way to prevent this is to have open tools and services. And pay for them. Read more

Easily Fund Open Source Projects With These Platforms

Financial support is one of the many ways to help Linux and Open Source community. This is why you see “Donate” option on the websites of most open source projects.
